Zinc dichromate ethers

Zinc dichromate tiihydrate, ZnCr207<3H20, is obtained as an orange-red solid by adding zinc carbonate to a cold solution of chromium trioxide in dilute sulfuric acid [660]. The applications are oxidations of acetylenes lo a-diketones, of aromatic hydrocarbons to quinones, of alcohols to aldehydes, and of ethers to esters and the oxidative regeneration of carbonyl compounds from their oximes [660]. [Pg.25]

By far the most important oxidation of ethers is their conversion into esters and lactones. Only a few reagents are capable of such a transformation ozone [110], chromium trioxide [539, 586], zinc dichromate [660], potassium permanganate [855], zinc permanganate [898], benzyltriethylam-monium permanganate [902], and ruthenium tetroxide (which gives the best yields) [774, 940] (equations 324 and 325). [Pg.169]

ZINC DICHROMATE (14018-95-2) An oxidizer. Reacts with reducing agents, alcohols, combustible materials, ethers, hydrazines, organic substances, metal powders. [Pg.1249]
